ECU Programming and Remapping

ECU remapping is when we take a read from the processing chip of the vehicle’s standard tuning map. By adjusting various parameters within the map – including fuel pressure, boost pressure, (on turbocharged applications) ignition advance, and throttle pedal control – we drastically improve your vehicle’s performance.

When a manufacturer develops a new vehicle, they take into consideration all driving conditions and regions in which they intend to sell this model. In other words, the tuning is a compromise. That’s why we rewrite or remap the vehicle’s engine software to safely gain more power and torque. This improves driveability and has the added bonus of enhanced fuel economy on diesel engines.

EGR Solutions

iTuning Auto Centre offers an advanced solution for exhaust gas recirculation (EGR). If the valves become clogged with carbon deposits, they may fail or stick, thereby causing error codes and affecting the vehicle’s ability to run correctly.

Our software solution is to disable the EGR valve; this is a simple and effective method of improving the efficiency of your engine. By reprogramming the engine management, we provide several benefits for your vehicle, including:

 Lowered Engine Temperatures

 Improved Throttle Response and Economy

 Longer Engine Life

 Reduced Oil Contamination and Carbon Deposits

Economy Remapping

With economy remapping, we take some of the strain off your engine and improve its efficiency and power instead. In addition to making your vehicle more environmentally friendly, this service reduces your throttle load and enables you to reach higher gears sooner and for longer. Best of all, fuel efficiency gains from this service are typically between 8 and 10 percent on most diesel vehicles, with more available when you choose our Quantum Green service. Whether you’re running your own car or a fleet of vehicles, it’s always good to save a little time and money.

OBD Remapping

OBD stands for On-Board Diagnostic, and we are able to provide comprehensive engine tuning and remapping using your vehicle’s OBD port. Using this, we are able to quickly diagnose faults, providing an early warning system before minor problems become major repair bills.

Performance Remapping

Explore the possibilities of your vehicle’s full potential with our performance remapping service. Our remapping software Is developed for standard petrol and diesel vehicles and designed to improve efficiency while maintaining manufacturer levels of reliability and original service intervals. With our Quantum Red calibration, you get a remap that is specifically designed for high power and ultimate performance.
